摘要: Photoluminescence experiments were carried out for Cd1-y Mny Te-Cd1-x Mnx Te-Cd1-y Te quantum wells with y >x . The magnetic field dependence of the exciton emission lines reveals paramagnetic effects which are markedly different from those bulk CdMnTe. It is shown that these consistent a clustering Mn ions. Furthermore, at low fields an additional energy shift in transition observed. This can be explained by formation polarons wells. polaron calculated as function strength and estimate localization radius made.
